Yes, nomodule support will be in the Fall Creators Update, and should have first appeared in Windows Insider flights starting with build 16241+. Not sure why the status of this still says "not yet flighted"…I’ll have to follow up on that.

This is only partially fixed. While Edge doesn’t execute the nomodule scripts, it still downloads them, incurring a performance penalty for the user. This makes the pattern that nukes most of the benefits of nomodule existence, i.e. including the following in HTML:

Every user should download just one file but Edge will download both. Other browsers (Chrome, Safari, Firefox) will only download the module one (once modules are enabled in Firefox which will happen soon).

Nolan: Thanks for the link. Do you have another issue for not downloading scripts with unrecognized types in general? That’s how Chrome & Safari behaves and Firefox is updating its behavior right now in https://bugzilla.mozilla.org/show_bug.cgi?id=838521.
